Ammoniac nitrogen enters salt of nitric acid of the translate into after soil, the chroma when arriving at groundwater is less than 30 milligram / litre, far be less than the lowermost standard with drinkable groundwater 氨氮进入土壤后转化为硝酸盐，到达地下水时浓度小于30毫克/升，远小于地下水饮用的最低标准。
We can divide every frame into similar chromatic regions, luminance changed regions and chroma changed regions and resolve the problem of inaccurate segmentation within luminance changing conditions 我们将图象帧划分成色彩相似区域、光照变化区域和色彩改变区域来进行判断，从而解决了亮度变化造成分割不准确的问题。
In this thesis, three-pan light engine system is discussed . on the base of chroma theory, a method for analysising and designing color separating and combining system is provided 本论文着重分析了三片式液晶光学引擎系统，在色度学理论的基础上，结合光学引擎系统，提出了一套分析设计该系统的分色合色部分的方法。
It is found that with concentration of eu3 " 1 " increasing, the fluorescent intensity is firstly rising then falling . a suited concentration of eu3 + is found that the fluorescent intensity is highest but the chroma leans to orange 随eu含量增加，磷光体余辉强度先增加后迅速降低，有一个最适宜掺杂浓度，此时余辉强度达到最高，但色度偏橙。
Many existing methods for image segmentation have been studied and compared in this thesis, and then an improved region growing algorithm is proposed-color image segmentation using chroma space based on block region growing 本文在比较和分析现有彩色图像分割技术的基础上提出了一种改进的区域生长算法??色度空间上基于子块区域生长的彩色图像分割方法。
There are many names for keying and while some are more accurate than others most people today jump between, chroma keying, keying, and blue or green screen compositing all are fairly much exactly the same thing 键控有很多名字和直到今天多数人用越来越精确的词来连接形容，像，色度键控，键控，以及蓝或绿幕合成方法，全部算是接近正确的，其实是相同的事情。
The experiment indicated that the technology process can acquire pricklyash seed oil whose acidity is appropriate at the level of losing, meanwhile the method can notably decrease chroma of the pricklyash seed oil 实验室试验表明稀溶液分步间歇式碱炼的工艺流程，可以在低炼耗的水平上得到酸值较理想的花椒籽碱炼油，同时该碱炼方法也能显著的降低花椒籽油的色度。
By analysising the thin film system, polarization and absorption of material, the relation ship between these parameters and the chroma of the light engine system is built . then a programm is writen in c + + language to realize the method 通过分析该系统从光源到分色合色和投影镜头的膜系结构，偏振特性，材料吸收等对系统能量分布的影响，建立了各个参数与系统色度之间的关系。
There is abundant of alga in raw water from july to september every year, a great deal of alga usually cause filter-stopping, higher turbidity and chroma of effusion, increasing the chlorine consumption, endangering the security of drinking water 在每年的79月湖水处于高藻期,大量的藻类进入处理构筑物常常造成滤池阻塞、出水浊度与色度偏高、氯耗增加,危及人们的饮用水安全。
So there ’ s a great correlation among the second bitplane . so we offered a new arithmetic coding scheme in which the design of context models is based on level and bitplane . considering the difference between luma and chroma coefficients, we will make it separately 由于abslevel=1的高概率出现,使得第二位平面具有很大的相关性,因此文中算术编码的上下文模型的设计方案主要基于level值和bitplane。
